FREDERICK W. STEINKE, OF OWATONNA, MINNESOTA.

FLEXIBLE-PIPE SYSTEM.

Specification of Letters Patent.

Patented Aug. 28, 1906.

Application filed September 23,1905. Serial No. 279,783-

To aZZ whom, it may concern:

Be it known that I, FREDERIOKW. STEINKE, a citizen of the United States,residing at Owatonna, in the county of Steele and State of Minnesota,have invented certain new and useful Improvements in Flexible-PipeSystems, of which the following is a specification.

This invention relates to that class of piping systems which are usedfor delivering skim-milk from creameries into cans located on wagonsbeside the creamery; and its object is to provide means for supportingflexible jointed metallic pipes, so as to relieve the joints from thestrain of the weight of the pipe, and means to retain thedelivery-nozzle in a position where its drippings, when not in servlce,will be conducted to a sewer.

To this end my invention consists in the construction and combination ofparts forming a fleXible-pipe'system hereinafter more fully described,and particularly set forth in the claim, reference being had to theaccompanying drawings, in wlnch Figure 1 is a perspective view of aflexible jointed pipe and a portion of a milk-can, showing t esupporting device, which is the main feature of this invention, inposition for service. Fig. 2 is a perspective view of the same deviceholding the nozzle of the pipe when not in service.

These illustrations represent the flexible jointed metallic pipe whichis the subject of my application, Serial No. 256,157, for apatent whichis allowed and to be issued October 3, 1905.

The pipe 3, projectin from the side of a creamery-building, is the maindeliveringipe, with which a radial pipe 4 is connected by a verticalpipe 5, which is free to rotate as a pivot, swinging the pipe 4 in ahorizontal plane.

6 is the delivery-arm of the pipe, having a nozzle 7 and connected withthe radialpipe 4 by an L-coupling 8, which has a rotary joint at 9,around which the pipe 6 may swing vertically to raise and lower thenozzle 7, and a rotary joint at 10, around which the pipe 6 may swing ina plane approximately horizontal. By means of the rotary joints 5 and 10the two pipes 4 and 6 may be swung about,

so as to bring the nozzle 7 over any point in quite a large field, thusenabling it to deliver into each can of a wagonful standing under it andalso to be located over a drain-pipe 11 when not in service.

12 is the handle of a valve whereby the flow of milk may be started andstopped.

In practice I have found that when the delivery-pipes are located far ateither side of the main pipe 3 their weight tends to rotate theconnections on pipes 3 and 4, thus displacing the nozzle and renderingit unreliable unless it is constantly held by an attandant while inservice, also tending to make the joint at 3 leak. To overcome this, Iprovide a rail 13, bent to the arc of a circle and rigidly fixedconcentric with the pivotal pipe 5 and in a horizontal plane, which isthe path of the lower side of the radial pipe 4, so that the latter inswinging on the said pivot slides upon and is supported by the said rail13 in all positions of service. When in service, the nozzle 7 enters themouth of a can 14, and the pipe 6 is supported on the edge thereof;otherwise the tendency of pipe 6 and its nozzle 7 is to hang down fromthe ivotal bearing 9, and if so left it woul deliver the drainings onthe ground. This would soon become sour and vitiate the air, and itwould also attract flies, both of which objections would be verydetrimental to the products of a creamery. I therefore locate adrainpipe 11 within the field of the nozzle 7 and a retaining-hook 15,on which the pipe 6 may rest and be steadily held when the nozzle 7 isover the drain-pipe. The radial member 4 of this piping system ispivoted at 5 to swing in a horizontal plane. The delivery member 6 ishung for horizontal and vertical movement, and the support not onlyholds its nozzle over the drain-pipe, but it keeps the free end fromhanging in the way of coming and gomg wagons.

Having thus fully described my invention, what I believe to be new, anddesire to secure by Letters Patent, is the following:

In piping systems, a flexible jointed metallic pipe having one of itsmembers pivoted to a fixture to swing in a horizontal plane; a curvedrail fixed in the said plane beneath the said member a delivery-pipepivotally connected with the aforesaid member; a be held in osition forits drippings to be drip-pipe located in the field of the deliverycaughtby t e said drip-pipe. 10 pipe, and a fixed support for the delivery- Intestimony whereof I afliX my signature pipe, substantially as describedwhereby the in presence of two witnesses.
